Bug Description

Using Ubuntu Phone music gets Pebble into factory mode (and also makes phone difficult to handle, because touching it sometimes has random effect).
Trying to reload firmware in this condition gets Rockwork locked into factory mode recovery (even when music is stopped, it reads 'upgrading' and won't respond, even when restarted).
Rebooting phone gets out of the lock. Then Rockwork will reload firmware, and things get back to normal - until I restart music.
No possibilty to uninstall Music on Pebble (which is probably responsible).
Logs following, before and after reboot.
